Ultra 150 Fuel Gauge issue

Well my fuel gauge is acting up, it reads either 2 bars or less regardless of how full the tank is.
I checked the resistance of the sender and it was correct for reading 2 bars (~4K ohms) but it would not read the full tank.

So, is it the float in the sending unit or the sending unit?
Can it be removed without moving the tank?

Had the same issue, my fuel gauge always read full. Here is what you have to do... First empty all fuel from the fuel tank, Mark all the lines that go into the sending unit with masking tape and label them so you know what goes where when you reassemble. Next remove the lines and disconnect the plug for the sending unit, now you can remove the 2 hose clamps that go around the rubber sleeve at the top of the sending unit. Next your going to need to unstrap the tie downs that hold the fuel and oil tank in place. It makes it easier if you also unhook the filler neck tubes for the fuel and oil tanks. Next you need to lift the front of the fuel tank up as far as possible, this will tilt the rear of the tank just enough to be able to slide the sending unit out behind the bracket that sits above the sending unit. 2 screws removes the cover to he sending unit and the float will be sitting in there somewhere. Clean the float and float pathway if it is gummed up, if not gummed up you may need to replace the sending unit as I did I think I paid $60 for a used one off eBay a few weeks ago. I hope this helps let me know how you make out. Good luck!!!
